Williamsport Regional Airport — Williamsport, United States

IPT is the code for Williamsport Regional Airport, serving Williamsport, Pennsylvania, a city best known as the home of the Little League World Series, held annually at nearby Lamade Stadium. The airport sees a notable seasonal surge every August as teams, families, and media travel in for the tournament, alongside its regular role providing scheduled flights connecting Williamsport to hubs like Philadelphia or Washington Dulles for business and regional travel. IPT also supports general aviation tied to the Susquehanna Valley's timber, manufacturing, and natural gas industries, including Marcellus Shale-related traffic. Its relatively small terminal handles a modest but steady mix of regional airline and charter operations throughout the year.
